Whats it like to be a navy nurse? im 18 an really thinking of joining the navy?

im an 18 year old female and i think that this would be a great experience for me! also i looked up a bunch of stuff online and i want to do the NROTC i think thats what it is... but they pay for all your college and then i'd get done with school and be a nurse.. idk what do you think?
